Poor customer service at Hyundai Springs

I recently bought a car from Hyundai in springs and from the onset they have been lying to me. I purchased a 2018 Hyundai i10 1.2. I dealth with Leon Brummer. When I got the dealership he had to boost the battery. I understand that due to lockdown the vehicle where not being started up. I drove the car back home to Durban. I sent an email to Leon from the dealership stating the car doesn’t want to start after 2 days. they sent in Hyundai Assist. He boosted the battery. The next day it never started. The boot board is warped that sits on top of the spare tyre. The 2 front tyres have around 40 % life. He never wants to reponds to his email but calls you directly and make promises. I had to send him an email to give the documents to register the vehicle. I don't understand how they get check their vehicles before they deliver to customers. How can this vehicle pass COR. Its not even a month now and I had to purchase a new battery. He has been promising me verbally. I got a call on Friday 4 September from a female from Hyundai customer service. She said she would speak to the dealer principal and get back to me. She never called. Bad service
